What safety measures apply during curtain wall glass repairs?

Safe curtain wall glass repairs depend on planning the work around the building, the glazing system and the condition of the damaged panel. GlassPlus UK assesses the risks before work starts, establishes a controlled working area and uses procedures that protect occupants, visitors, operatives and the building itself.

Key safety measures typically include:

• Pre-work risk assessment: The repair team considers the location of the panel, the extent of the damage, the surrounding structure, access routes and any hazards created by broken or unstable glass. This assessment informs the method of removal and installation.
• Exclusion and warning arrangements: Areas beneath and around the work position may need to be restricted so that people cannot pass beneath lifting operations or approach damaged glazing. Barriers, signs and controlled routes help separate the repair from normal building activity.
• Secure access: The selected access method must be suitable for the height, façade layout and available ground conditions. Equipment is positioned on stable surfaces and checked before use, with the working area arranged to avoid unnecessary movement or contact with adjacent panels.
• Careful removal of damaged glass: Broken or compromised panes are handled in a way that limits further cracking, falling fragments and damage to the frame. The team also takes account of retained glass, gaskets, beads, sealants and other components that could affect the stability of the unit.
• Controlled lifting and positioning: Replacement glass is moved using equipment and techniques appropriate to its size and weight. Clear communication between the people involved is essential when guiding the pane into the curtain wall frame.
• Protection of adjacent finishes: Internal floors, furnishings, façade materials and nearby fixtures can be protected from impact, glass fragments and installation materials. This is particularly important where repairs take place close to entrances, reception areas or occupied workspaces.
• Consideration of weather conditions: Wind, rain, temperature and visibility can affect safe handling and access on an external façade. Work is planned around the conditions present at the time, rather than treating every repair location in the same way.
• Safe removal of waste: Broken glass, old sealants and redundant components are gathered and removed in a controlled manner. The area is checked afterwards so that no sharp fragments or obstruction remain for building users.
• Final inspection: Once the replacement is installed, the glazing, frame and surrounding area are checked for secure fitting, damage and any issues requiring attention. The completed work should leave the repaired section safe for its intended use and compatible with the surrounding curtain wall system.

For occupied commercial premises, the repair plan should also reflect the building’s daily activities. GlassPlus UK can take account of entrances, pedestrian routes, tenant areas and other operational constraints when arranging the work. Clear communication with the responsible person on site helps ensure that access restrictions and safety controls are understood before the repair begins.

Businesses comparing contractors should look for evidence that safety is integrated into the repair method, rather than treated as a separate formality. GlassPlus UK brings more than 30 years of industry experience to commercial glazing work and carries out repairs in accordance with current building and safety regulations. Its approach is to identify the specific risks at each curtain wall location and apply controls suited to the system and site conditions.
